Hi there, I am considering to buy a Drobo S with 4 x 2TB 7200 rpm hard drives to store my HD TV Shows / Movies downloads. These are 720p files purchased from iTunes. I intend not to use the Drobo as a spare Time Machine back-up, but like an external hard drive with built-in redundency. After moving all of my media files to Drobo, I want to be able to play them straight from there in iTunes / QuickTime. However, I have read several reviews that said that Drobo S is slow even with a FireWire 800 connection. Will this be a problem if I want to play a movie file from there? Thanks for helping.
